SN74AHCT00PWE4

Overview

The SN74AHCT00PWE4 is a quadruple 2-input positive-NAND gate from the Texas Instruments SN74AHCT00 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low output currents of 8 mA for both high and low states. The device exhibits a propagation delay of 5.5 ns and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a TSSOP-14 surface-mount format, this component integrates four independent NAND logic gates suitable for digital signal processing applications requiring CMOS compatibility with TTL input levels.

Feature Summary

• Integrates four independent 2-input NAND logic gates within a single package
• Ensures CMOS compatibility while accepting standard TTL input voltage levels
• Provides robust performance with specified low-level and high-level output drive capabilities

Applications

• Digital logic signal processing circuits
• Microcontroller interface gate arrays
• General-purpose boolean logic implementation

Procurement Notes

Verify the specific suffix E4 indicates lead-free manufacturing compliance when sourcing replacements. Confirm the TSSOP-14 package dimensions match your PCB footprint requirements. Ensure the 4.5 V to 5.5 V supply voltage constraint aligns with your system power rails. Check for RoHS directive adherence if required by your assembly standards. Validate that the -40°C to +85°C industrial temperature rating meets your environmental specifications.

Selection Notes

Select this component when TTL-compatible inputs are necessary alongside CMOS noise immunity. The AHCT series bridges the gap between older TTL systems and modern CMOS designs. Consider the 5.5 ns propagation delay for timing-critical paths. The TSSOP-14 package offers space efficiency for dense board layouts. Verify that the 8 mA output current suffices for your load requirements without external buffering.

Part Context

This part belongs to the SN74AHCT00 family of quad 2-input NAND gates manufactured by Texas Instruments. The AHCT designation signifies High-speed CMOS technology with TTL-compatible inputs. The PWE4 suffix denotes the TSSOP-14 package type and lead-free construction. This series is designed for general-purpose digital applications requiring reliable logic switching.
